"The typical Okinawan reaching 110 years of age has had a diet consistently averaging no more than one calorie per gram" So if I weigh 60k I can eat 60,000 calories??? —Preceding unsigned comment added by Turgonml (talk • contribs) 18:18, 20 May 2008 (UTC)

Reversion
I reverted the article to a previous version for a couple of reasons. First, it had many contradictions. The article states that this diet is a low-calorie diet and has only 75% of the grains of the typical Japanese diet, yet the new material stated that the vast majority of their calories came from carbs. Were this true, it would not be a low-calorie diet. Also, the only reference added by the previous version is biased and starts with the conclusion, and does not support all the facts in the previous version. Okinawa is known as "The Island of Pork", and those who have been there will attest to the fact that they have a very high-fat diet. Shicoco (talk) 19:16, 14 November 2011 (UTC)
 * The statement that the majority of their calories came from carbs is supported by Willcox (2007) and by Willcox (2009), both of these sources say that the diet is 85% carbohydrate based. Why is it impossible for a high-carb diet to be a low-calorie diet at the same time? The primary source of calories is the sweet potato, which only has 1 calorie/gram or even less (nutritiondata.com quotes boiled sweet potato as having 0.76 calories/gram). It is quite difficult for a human being to eat much more than 2 kg/day of food. Low energy density of sweet potato is what makes the Okinawa diet "work" - that's what makes it low-calorie despite being high-carb.
 * The reference to ci.nii.ac.jp, which was in the article before I got here, quoted consumption of pork on the island in 1979 as less than half of consumption of pork in the United States today, and less than one tenth of total meat consumption in the United States. I've never been to Okinawa but the source seems credible to me.
 * If you have any sources that give hard numbers with regard to consumption of pork or fat, let's see them. All we have in the article and its references right now is vague statements.--Itinerant1 (talk) 11:00, 15 November 2011 (UTC)
 * P.S. The statement that the traditional Okinawa diet has 75% of the grains of the Japanese diet seemed questionable to me. Willcox (2007) reports the following figures for Okinawa and Japan in 1949/50:
 * Okinawa: 192 g grains, 965 g of vegetables, and 3 g of meat per day
 * Japan: 481 g of grains, 301 g of vegetables, and 11 g of meat per day
 * Clearly these numbers are in conflict with the claim of "75% of the grains". But that claim may have been made with regard to the contemporary rather than traditional Okinawa diet, and I couldn't check the original source cited.--Itinerant1 (talk) 11:08, 15 November 2011 (UTC)
 * Even if you think that Willcox is biased, here's an article by an unrelated author dated 2001. Apparently Okinawans love their pigs, and they often eat them on holidays, but their _everyday_ diet is still very-high-carbohydrate: for teachers and public officials, this article reports the dietary composition of 42 g of protein, 4 g of fat, and 546 g of carbohydrates per day. --Itinerant1 (talk) 12:01, 15 November 2011 (UTC)

The arguments here make no sense. A diet being high-carb and being low-calorie is not mutually exclusive. Someone seems to be thinking calorie and carb are interchangeable. Sounds like paleo-nutjob thinking to me. Even if the diet were all carbs it could be low calorie provided they ate few calories. — Preceding unsigned comment added by 67.171.165.123 (talk) 05:39, 3 May 2012 (UTC)

Decline in life expectancy
More recent "An Age of Centenarians? Lifelong Learning Policies and Ageing" http://ghrforum.org/design/ko/pdf/(TA-4)PETER_JARVIS.pdf) slide 18:

The Reality:
 * But by 2005 changes were taking place amongst the Okinawans – some 100,000 emigrated to Brazil and they immediately assumed a Brazilian diet and the life expectancy of these Okinawans is now 17 years lower than that previously in Okinawa –
 * but things are also changing in Okinawa too: the younger generation have discovered fast food and men under 50 in Okinawa now have Japan's highest rates of obesity, heart disease and premature death (Wiseman, 2008 [2002]).

Calorie Restriction - Not True
I looked at all the available data listed, the idea that the traditional diet was calorie restricted came from data right after World War 2, obviously they were calorie restricted after getting blown to bits by a huge battle.

The data from 1919 however shows the average person consuming 3200+ calories a day average and the upper-class consuming 2200. This can hardly be considered "calorie restricted". I'm going to edit the article. — Preceding unsigned comment added by 180.190.183.29 (talk) 12:31, 23 November 2012 (UTC)

Quasi-Vegan
After reviewing all the available dietary data from 1880, 1919, and 1950. It appears that these people did not eat milk or eggs, ate meat once per month, and consumed fish as 1% or less of their total calorie intake.

Relapsing vegans take in more animal product than this, I labeled them quasi-vegan. — Preceding unsigned comment added by 180.190.183.29 (talk) 12:53, 23 November 2012 (UTC)

This is not a vegan thread and Okinawa people are not vegan
Where did you take this information ? if they eat more pork than the average Japanese then their diet is not a majority of plant based. The sentences clash with each other and i have to say the quantities shown in here are not true. nobody of them has experienced veganism as it is a way of life starting with the rise of the internet. for more info : www.beyondveg.com and it is also written that they eat less sugar. well, sugar is carbs, so it couldn't even make sense. if almost of their entire diet is plant ,they would consume a lot of sugar,as plants of course. 79.183.49.156 (talk) 12:39, 23 January 2015 (UTC)
